Abstract
A scanning method for high-speed reproduction of video data from a recording disk, whereby scanning is executed as a sequence of track jump operations, in which the data detection point of the pickup is caused to jump across tracks of the disk, alternating with intervals of play operation in which data are read from the disk. During each interval of play operation, data obtained from the disk are written into a memory, and thereafter are repetitively read out from the memory to produce an output video signal, until being updated during the next play interval. A display image that is free from noise and disorder is thereby obtained during scanning operation.
